French composer Bruno Coulais (Winged Migration and The Chorus) is without a doubt, a musical genius, and Microcosmos is one of the best examples of his work. The music is very mysterious, a bit eerie and yet very sweet. The film Microcosmos, is a documentary of detailed insect interactions in meadows and ponds all set to his score.

The title track Microcosmos sounds like a cross between a typical English or Welsh choir song, something along the lines of the surreal musical tunes created by Danny Elfman for Nightmare Before Christmas and The Corpse Bride.
